Specification of Letters Patent.

Patented Mar. '7, 1916.

Application filed November 6, 1913. Serial No. 799,464.

Be it known that I, DANIEL'SEXTON, a citizen of the United States, residing in Kansas City, in the county ofJackson and State of Missouri, have inventedcertain new and useful Improvements in Machines for Forming Recesses in Insoles, of which the following is a specification. I

My invention relates to improvements in machines for forming recesses in insoles.

The object of my invention is toprovide a machine by which recesses may be cut in one side of an inner sole, whereby depressions may be formed to receive-salient portions on the foot of a person wearing a shoe containing the inner sole, as described in the patent granted to me November 15, 1910, No. 975,576.

The novel features of my invention are hereinafter fully described and claimed. 5

In the accompanying drawings which illustrate the preferred embodiment of my invention, Figure l is a plan view of the machine, showing insoles in the holders, and one insole disposed inthe position adapted for having recesses cut therein. Fig. 2 is an elevation of the machine. Fig. 3 is a vertical sectional view on the line ab of Fig.1, the insoles being removed from the holders, one insole being shown in position for cutting.

is a perspective view, enlarged,v of one of the members which supportsone of the clamping plates. Fig. 17 is a perspective view of one of the clamping plates enlarged.

Similar reference characters designate similar parts in the different, views.

1 designates a frame of any suitable material, size and form provided with horizontal guides 2 on which are reciprocatively mounted two supports comprising preferably two horizontal plates 3 each provided with carrying wheels 4 adapted to run on the guides 2. The supports 3 are'respectively provided with fiat horizontal surfaces adapted to respectively support two piles of insoles 5 contained within twoholders respectively. Each holder comprises preferably two horizontal bars 6 having screwthreaded ends slidably mounted in horizontal slots 7 provided in opposite vertical sides of the frame 1 as is shown in Figs. 2 and 3. The bars 6 have nuts 8 mounted thereon and adapted to bear against the frame 1. Secured to each bar 6 are two vertical guide bars 9, adapted to bedisposed against the pile of inner soles contained within the holder. The bars 9 may be adjusted toward and from the insoles to correspond with the width of said insoles. V g

Mounted on a horizontal plate 10 which forms a part of the frame 1 are two supplemental frames 11 and 12, the frame 11 being rigidly secured to the plate 10 and the frame 12 being horizontally slidable to and from the frame 11. The frame 12 is provided with'vertical bolts 13 which extend down frames 11 and 12 respectively are two horiz'ontal shafts 18 and 19, each of which has secured to it adjacent to opposite ends thereof two rotary cutters 20, the particular con:

struction of which will. behereinafter described. For rotating the shafts 18 and 19 said shafts have respectively secured to them, as shownin Fig. 8, two worm wheels d 2.2. Which nieshrespectiv ly Wit t o worms 23 and 24 which are secured to a horizontal shaft 25 rotatably mounted in a bearing 26, which is supported by plate 10, and a bearing 27 secured to the'frame 1. A pulley 28 is secured to the shaft '25 for driving the same. The worm 24 is longitudinally slidable on the shaft. 25 with the supplemental frame 12 through which said shaft extends.

Secured to the supplemental frame 12 is a horizontal bar 29, Fig. 1, whichhas secured to it adjacent to its respective ends two vertical guide bars 30 which serve as guides for the heel ends of the piles 5, each bar being located between a. pair of the bars 6. The bars and the bar 29 are adjustable with the supplemental frame 12 to correspond with the length of the insoles 5.

As shown in Fig. 1 a transverse horizontal guide bar 31 is adjustable on the plate 10 toward, and from the bar 29 and is provided at its ends with two upstanding projections 32 disposed respectively between the two pairs ofbars 6, and are adapted to serve as guides for the toe'ends of the piles 5. Bolts 33 extend through the bar 31 and through longitudinal slots 31 provided in the plate 10. The bolts 33 have mounted on their upper ends nuts 35 which are adapted to bear against the upper side of the bar 1 for retaining it in position.

As shown in Fig. 1 and in Fig. 4 each plate 3 is provided with slots 36 in which are respectively mounted two U-shaped stops 37, the downwardly extending arms of which slidabljv embrace one set of arms of two right-angled horizontal plates 38 each of which is provided with a slot 39 through which extends a clamping thumb screw 10 the upper end of which has screw-threaded engagement withthe plate 3. 7 By loosening the said thumb screw the plate 38 may be moved so as to adjust the stop 37 on the slot 36. To normally retain each stop 37 in the elevated position shown in Fig. 4, in which position it is adapted to strike the outer edge of the lowest adjacent insole, each stop is provided with a vertical screw 41, F igfil, which is slidably mounted in a downwardly extending tubular projection 42 on the under side of the plate 38. A coil spring 43, mounted in a recess 44: in the plate 38 and encircling the screw 11 exerts a tension which normally holds the stop 37 in the elevated position. As shown in Fig. 4 the upper end of each stop 37 is inclined downwardly and outwardly, which permits the '37 will engage the outer edges of the lowest secured horizontally in the frame 1. tached to the spur gear wheel 51 is a spur insoles in the two piles and will carry'the insoles thus detached to positions under the cutters 20. In Fig. 1 I have shown the right plate or support 3 in the inner position with one of the insoles 5 detached from the pile and positioned under the two right rotary cutters Thesupports or plates 3 are disposed at a height such that the cutters 20 inrotating will pass through the material in the upper side of the insoles when said insoles are inthe cutting position, as shown in Fig. 3. The cutters 20 on each of the shafts 18 and 19' are disposed in diametricallylopposite positions, so that when one cutter is operatingon an insole the other cutter will'be raised so as to permit an insole passing thereunder. For alternately reciprocating the two plates 3 these plates have respectively secured pivotally to them gear wheel 53 which meshes with a spur gear wheel 54 securedon the shaft 25. The shape of the groove 48 in the cam 49 is such that the levers 46 will alternately force the plates ,3 from the outer to the inner position,an'dduring one-half of a revolution of said cam will'hold said plates in the-inner position during the cutting operation of the cutters 20. The worm wheels 2] and the gear wheels 50, 51, 53 and 54: are of such relative sizes and have such number of teeth that during each revolution of a cutter 20 the adjacent plate 3 will makeone complete reciprocation.

When the shaft 25 is rotated the plates 3 will alternately be moved from the outer position to the inner position and will carry inwardly, each, an inner sole to a position in which said inner sole will have its inner edge strike-against two outwardly extending horizontal screws 55, Fig. 1, mounted respectively on the supplemental frames 11 and 12. The screws 55 may be adjusted in- Wardly and outwardly to suit the widths of the insoles which are being operated upon. After the cutters 20 have out two recesses in the inner sole which has thus been fed inwardly, and the cutter has become detached from said inner sole, the plate carrying said insole will move outwardly, and the stops 37 carried by said plate 3 will pass under the adjacent pile 5 and will engage v with the outer edge of the bottom insole in the adjacent pile, saidpile having dropped by gravity the thickness of the insole which had just been previously detached from said 7 bearii'ig upon the projection 61 at the inner, sides of the screws 63 serve to tilt the plates pile. As the plate 3 moves outwardly the insole 5 which has been cut will drop from r provided with a screw threaded hole in which is fitted a horizontal screw threaded rod .57 having a T-headed outer end pivotally mounted in a longitudinal .T-shaped groove 58 provided in a screw 59 fitted in a transverse screw threaded hole provided in the adj acent plat-e6. The rod 57 .is pivoted so as to permit an insole when being detached from the pile swinging the said rod and the stop plate 56 carried by it, up

wardly, so as to permit the inward'movement of the said insole.

For the purpose of clamping the insoles tightly against the supporting plates S-the following describedmechanisms are provided: Four rectangular plates 60, one of which is shown in Fig. 16, are provided each at its inner edge with two inwardly extending projections 61, havingeach a vertical hole 62. Each end of each of the frames 11 and 12 is provided with two vertical threaded holes in which are fitted respectively two vertical screws 63 which extend through and are loosely fitted in the holes 62 of the adjacent plate 60. Eight coil springs 64, one of which is shown in. Fig. 13, respectively encircle the screw 68 and by 60 upwardly at their outer edges. 'Four clamping plates 65 having theirlower sides provided with teeth 66, Fig. 15, for engage ment with the upper-sides of the insoles, are respectively supported by the platesbO, and are vertically movable, and are also movable parallel with the upper surfaces of the plates 3. The upper side of each of the plates 65 is provided at opposite ends, as is shown in Fig. 17, with beveled surfaces 67 which are adapted to engage similarly beveled surfaces 68, Fig. 12, which are provided on the under side and opposite ends of each of the plates 60. For yieldingly supporting the plates 657fron'1 the plates 60 each of the plates 60 is provided at its opposite edges with two horizontal pins 69,

which extend into and are slidably mounted respectively in two inclined slots 70 providedrespectively in'two plates 71 disposed at opposite edges of the adjacent plate 60. Each plate 71 is provided at the end opposite the slot 70 with an upwardly inclined extension 72 slidab-lv mounted be-" tween two horizontal pins 73 which extend horizontally from the adjacent edge of the plate 60, see Fig. 10. Encircling each extension 72 is a coil spring 74 the lower end of which bears against the pins 78 and the upper end of which bears against a nut 7 5 which is mounted upon the screw threaded ofthe spring 74; is such as will cause the adjacent plate '71 to be moved upwardly to the position shown in Fig. 9. A coil spring 76 has its lower end secured to a horizontal pin 77. provided at the edge ofthe plate The upper end of the coil spring 7 6 is attachcd'to the adjacent plate.

71. It will be understood that two springs 76 are provided respectively at the inner and outer edges ofeach clamping plate 65, as shown in Fig. 11. The tension of the springs 76 is such that the plates 65 will be drawn upwardly and with the inclined surfaces I67 against the inclined surfaces 68 of the plates 60. At opposite edges of each clamping plate 65 are rigidly secured're spectively two plates 78, Figs. 11 and 15 each of which is provided with two horizontal inwardly extending pins 7 9 mounted respectively in the adjacent slot/ of the plate '71 and above the adjacent extension 7 The pins 79 by resting upon the plates outer end oftheextension 72. V The tension I 71 serve to support the clamping plates in'the position shown in Fig. 15. ing the plates'65 tightly against the upper sides of the insoles each of the shafts 18 and 19 has secured to it two pairs of cams For forc- 80, each pair being adapted to come in con-f tact with the uppers-ide of one of the plates 60, and to also come in Contact withthe upper edges of the adjacent plates 71, for

the purpose of forcing said-plates to the clamping positions shown in Figs. 10, 11

and'12. The relative arrangement ofthe plates.60,-65 and 71 and of the cams 80 and rotary cutters 20, is such that when the cutters 20 are passing through the material of the insoles '5, as shown in Figs. 10, 11 and 12,'the cams 80 will be in the positions shown in Figs. 10' and 12, in which positions.

which is of circular form in a plane which is perpendicular to the axis of rotation-of the cutter 20, as shown in Figs. 9 and 12.

As shown in Figs. 1 and 9 the cutting edge 82 of each of the blades 81 is disposed obliouely to thepath of movement of said blade and. tothe. axis of the cutter 20 carrving said blade. By means of this form of the blade it will, in passing throughv the insole, cut a curved recess in the-upper side thereof, and the cutting edge of the'blade will be drawn lengthwise through the material instead of being forced at right-angles thereto. thereby making the blade cut more easily and smoothly. To hold the portion which is cut out by the blade 81 in position until the blade has passed entirely free from the. materialof the insole, each plate 6 5 is -covering Set against the under side of which the cut-out portion of the insole is adapted to bear during the cutting operation. The

abutment 83 and its covering 8% thus prevent the blade 81 from tearing the cut-out portio'n'from the body of the insole and holds'said cuto'ut portion firmly in position until the cutting operation has been performed. It will be understood that each of theplates 60 is provided with a vertical hole 84 therethrough to permit the revolution of the outter 20. In like manner and for like purpose each of the plates 65 is provided with a vertical hole 85 therethrough. Toequalize the .end thrust on the shaft the worms 23 are provided respectively with right and left threads, whereby the shafts 1.8 and 19 are rotated in opposite directions, and for this reason the cutters 20 on corresponding ends of the shafts 18 and 19 have their blades oppositely disposed and said cutters are arranged to have their blades simultaneously effect the cutting operation.

As has already been. described when the shaft 25 is driven by-the'pulley 28 the cutters 20 will be rotated and the plates 3 will be alternately reciprocated by means ofa mechanism which has already been described. As each of the plates 3 moves inwardly it will detach from the 'adjacent pile 5 and carry with it the lowest insole of sald pileand, when the plate is in the innermost position, shown at the right in Flg. 1, the detached insole 5 will be disposed under the two adjacent clamping plates 65 and with its inner edge disposedagainst the adjaeent adjustable stop screws 55, and the cutters 20, cams 80 and plates 60, 65 and 71' will be in the positions shown in Fig. 9,

' the plates and in a direction correspond said plates being raised to permit the passage under the plates 65 of the detached 1nsole 5. Continued. revolution of the shafts l8 and 19 will bring the cams carried thereby against the upper sides of the adjacent plates 60, andagainst the upper edges of the adjacent plates 71 depressing said plates and therebypermitting the clamping plates '65 carried therebyto lower agalnst the upper side of the detached insole 5. When the cams 80 have been moved to the position shown in. Figs. 10, 11 and 12 the springs 76 will have drawn the plates 65 horizontally with the inclined surfaces67 thereof against the inclined surfaces 68 of ing to the path of movement of the cutting blades 81 through the material of the insole.

The cutting blades 81 in passing through the material of the insole will have a tendency to carry with them the insole which being engaged with the teeth '66 0f the plates 65 will force said plates more tightly against the inclined surfaces 68, the inclination of the insole will be held by the abutments 88 in position until the blades have entirely severed'said material from theinsole. After thls has been accomplished, the plate 3, carrying the insole, will be moved outwardly by means of the cam a9 and the mechanism connected therewith and already described, and the insole with the recesses formed therein will have its outer edge brought against the stop 56 which will hold the insole from further outward movement until the support 3 has been withdrawn from the insole upon which the insole will fall by gravity. .After the insole has dropped and the plate 3 carrying it has reassumed its outermost position, the opposite plate 3 will have been moved to the innermost position, and will have detached from the other pile the lowermost insole thereof and placed it under the other set of cutters 20. The other sets of clamping devices will then clamp the insole so positioned and the other two cutters will form the two recesses in said insole in the manner already de scribed. After this has been done the left plate 3, as viewed in Fig. 1, will again move outwardly and the right plate 3 will move inwardly thus detaching and positioning another insole, after which the operation hereinbefore described will be repeated.
